Abstract
The smelting is carried out in a reactor with adjacent oxidation and reduction zones, the slag baths of both zones communicating with one another, the materials being charged to the slag bath in the oxidation zone and oxygen-containing gases being blown into the slag bath, a slag having a high content of non-ferrous metal oxides being passed from the oxidation zone into the reduction zone, reducing agents and oxygen-containing gases being blown in the reduction zone into the slag in such quantities that the non-ferrous metal oxides are almost completely reduced and a phase rich in non-ferrous metals is formed, a slag low in non-ferrous metals being taken off from the reduction zone, the gases from the oxidation zone and from the reduction zone being extracted separately, and the reduced pressures in the extraction lines from the oxidation zone and from the reduction zone being adjusted such that the differential pressure is zero approximately at the boundary between the oxidation zone and reduction zone.
